NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Three Months Ended March 31, 2007 and 2006 (unaudited)
Note 1 — Organization and Summary of Significant Accounting Policies
Interim Reporting
     In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the financial position as of March 31, 2007, and the results of operations and cash flows for the three months ended March 31, 2007 and 2006. The unaudited consolidated financial statements are presented in accordance with the requirements of Form 10-Q and do not include all disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”). Reference should be made to our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended 2006, which include certain definitions and a summary of significant accounting policies and should be read in conjunction with this Quarterly Report on
Form 10-Q.
Organization
     Harvest Natural Resources, Inc. is engaged in the exploration, development, production and management of oil and natural gas properties. We conduct our business principally in Venezuela through our subsidiary Harvest Vinccler, S.C.A. (“Harvest Vinccler”) in which we indirectly own an 80-percent interest. Effective April 1, 2006, our activities under our Operating Service Agreement (“OSA”) are reflected under the equity method of accounting. Since such activities are subject to the completion of the conversion of the OSA to Petrodelta S. A. (“Petrodelta”), we have not recorded any net earnings from such activities since April 1, 2006, including the three months ended March 31, 2007.
     On March 31, 2006, Harvest Vinccler signed a Memorandum of Understanding (the “MOU”) with two affiliates of PDVSA, Corporación Venezolana del Petroleo S.A. (“CVP”) and PDVSA Petroleo S.A. (“PPSA”), to convert the OSA into a minority interest in Petrodelta. Upon receipt of the Venezuelan government approvals contemplated by the MOU, Harvest Vinccler, HNR Finance B.V. and CVP will enter into a Contract of Conversion (the “Conversion Contract”). Upon execution of the Conversion Contract, Petrodelta will be formed. Subject to the conditions of the Conversion Contract, the OSA will be cancelled, Harvest Vinccler will transfer substantially all of its tangible assets and contracts, permits and rights related to the Uracoa, Tucupita and Bombal fields (“SMU fields”) in Venezuela to Petrodelta and Petrodelta will engage in the exploration, production, gathering, transportation and storage of hydrocarbons from the SMU fields, as well as the Isleño, Temblador and El Salto fields which will have been awarded to Petrodelta as a condition of conversion. Upon completion of conversion, HNR Finance B.V. will have a 40 percent ownership interest in Petrodelta. Since we indirectly own 80 percent of HNR Finance B.V., we will indirectly own a net 32 percent interest in Petrodelta and our partner, Oil & Gas Technology Consultants (Netherlands) Coöperatie U.A., a controlled affiliate of Venezolana de Inversiones y Construcciones Clerico, C.A. (“Vinccler”), will indirectly own a net eight percent interest. CVP will own the remaining 60 percent. At our request, CVP has added HNR Finance B.V. as a party to the Conversion Contract. Petrodelta will be governed by its own Charter and By-Laws.
Principles of Consolidation
     The consolidated financial statements include the accounts of all wholly-owned and majority-owned subsidiaries. The equity method of accounting is used for companies in which we have significant influence. All intercompany profits, transactions and balances have been eliminated.
Reporting and Functional Currency
     The U.S. Dollar is our functional and reporting currency.

Table of Contents

Revenue Recognition
     Oil and natural gas revenue is accrued monthly based on production and delivery. Until March 31, 2006, each quarter, Harvest Vinccler invoiced PDVSA Petroleo S.A., an affiliate of Petroleos de Venezuela S.A. (“PDVSA”), based on barrels of oil accepted by PDVSA during the quarter, using quarterly adjusted U.S. Dollar contract service fees per barrel. The related OSA with PDVSA provided for Harvest Vinccler to receive an operating fee for each barrel of crude oil delivered and the right to receive a capital recovery fee for certain of its capital expenditures, provided that such operating fee and capital recovery fee could not exceed the maximum total fee per barrel set forth in the agreement. In August 2005, Harvest Vinccler and PDVSA executed a Transitory Agreement (the “Transitory Agreement”) which provided that the maximum total fee per barrel paid under the OSA could not exceed 66.67 percent of the total value of the crude oil as determined under an Annex to the Transitory Agreement. This limitation was applied retroactively to January 1, 2005 and approximates 47 percent of West Texas Intermediate (“WTI”). The operating fee was subject to quarterly adjustments to reflect changes in the special energy index of the U.S. Consumer Price Index. Until March 31, 2006, each quarter, Harvest Vinccler also invoiced PDVSA for natural gas sales based on a fixed price of $1.03 per Mcf. In addition, Harvest Vinccler agreed to sell to PDVSA 4.5 million barrels of oil stipulated as additional volumes resulting from the natural gas production (“Incremental Crude Oil”). A portion of the Incremental Crude Oil was invoiced to PDVSA quarterly at a fixed price of $7.00 per Bbl. The invoices were prepared and submitted to PDVSA by the end of the first month following the end of each calendar quarter, and payment was due from PDVSA by the end of the second month following the end of each calendar quarter. Harvest Vinccler has recorded deferred revenue of $9.0 million for 2005 and first quarter 2006 deliveries pending clarification on the calculation of crude prices under the Transitory Agreement.
     As of March 31, 2007, the conversion to Petrodelta had not yet been completed pending approvals by the Venezuelan government. In April 2006, the Venezuelan National Assembly passed legislation unilaterally terminating all operating service agreements and directing the government to take over the operations carried out by the private companies without prejudice to the incorporation of mixed companies for that purpose. This action, coupled with the unfinished conversion to Petrodelta, left Harvest Vinccler without a contractual means recognized by the government of Venezuela to address revenues or costs and expenses since March 31, 2006. As a result of this situation, our consolidated financial statements prepared in accordance with GAAP for the three months ended March 31, 2007 do not reflect the net results of our producing operations in Venezuela. We will not be able to include the results of our Venezuelan operations in our consolidated financial statements until the conversion to Petrodelta is completed or there is a contractual means recognized by the government of Venezuela to address revenues, costs and expenses. Although the MOU provides that there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006, this adjustment will not occur until the conversion is completed. Harvest Vinccler continues in the day-to-day operations of its properties in Venezuela and continues to incur expenses in doing so. The equity method of accounting will be followed for Petrodelta to reflect our net 32 percent interest. At March 31, 2007, Harvest Vinccler had advances outstanding to PDVSA of $17.2 million, of which $9.6 million had been reimbursed through April 25, 2007.
Cash and Cash Equivalents
     Cash equivalents include money market funds and short term certificates of deposit with original maturity dates of less than three months. At March 31, 2007, Harvest Vinccler had 25.4 billion Venezuela Bolivars (“Bolivars”) which are shown in the March 31, 2007 financial statements as $11.8 million in cash and cash equivalents.
Restricted Cash
     Restricted cash represents cash and cash equivalents held in U.S. banks used as collateral for Harvest Vinccler’s line of credit and loan agreements, and is classified as current or non-current based on the terms of the agreements. See Note 2 – Long-Term Debt.
Minority Interests
     We record a minority interest attributable to the minority shareholder of our Venezuela and Barbados subsidiaries. The minority interest in net income and losses is subtracted or added to arrive at consolidated net income.

Table of Contents

Earnings Per Share
     Basic earnings per common share (“EPS”) are computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. The weighted average number of common shares outstanding for computing basic EPS was 37.4 million and 37.1 million for the three months ended March 31, 2007 and 2006, respectively. Diluted EPS reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. The weighted average number of common shares outstanding for computing diluted EPS, including dilutive stock options, was 37.4 million and 38.5 million for the three months ended March 31, 2007 and 2006, respectively.
     An aggregate of 1.7 million and 2.1 million options were excluded from the earnings per share calculations because their exercise price exceeded the average price for the three months ended March 31, 2007 and 2006, respectively.
Stock-Based Compensation
     At March 31, 2007, we had several stock-based employee compensation plans, which are more fully described in Note 5 in our Annual Report on Form 10-K for the year ended 2006. Prior to 2003, we accounted for those plans under the recognition and measurement provisions of Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. Effective January 1, 2003, we adopted the fair value recognition provisions of SFAS Statement No. 123 (“SFAS 123”), Accounting for Stock-Based Compensation, as amended by Statement of Financial accounting Standards No. 148 (“SFAS 148”), prospectively to all employee awards granted, modified, or settled after January 1, 2003. Effective January 1, 2005, we adopted Statement of Financial Accounting Standard 123 (revised 2004) Share-Based Payment (“SFAS 123R”) to all employee awards granted, modified, or settled after October 1, 2005. Awards under our plans vest in periodic installments after one year of their grant and expire seven to ten years from the grant date. Therefore, the cost related to stock-based employee compensation included in the determination of net income in three months ended March 31, 2006 is less than that which would have been recognized if the fair value based method had been applied to all awards since the original effective date of SFAS 123. The following table illustrates the effect on net income and earnings per share if the fair value based method had been applied to all outstanding and unvested awards in each period.

New Accounting Pronouncements

Table of Contents

     In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard 159 – The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value. SFAS 159 is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FASB Statement No. 157 – Fair Value Measurements. When adopted, SFAS 159 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

     On September 27, 2006, Harvest Vinccler entered into a three year term loan with a Venezuelan bank for 105 billion Bolivars (approximately $48.8 million). The first principal payment is due 360 days after the funding date in the amount of 21 billion Bolivars (approximately $9.8 million), and 21 billion Bolivars (approximately $9.8 million) every 180 days thereafter. A payment in the amount of 20 billion Bolivars (approximately $9.3 million) was made on December 18, 2006. The interest rate for the first year is fixed at 10.0 percent and will be renegotiated for the second year subject to a maximum of 95 percent of the average interest rate charged by six major Venezuelan banks. This loan is collateralized by a $32.3 million deposit plus interest in a U.S. bank. The loan was used to meet the SENIAT income tax assessments and related interest.
     On October 3, 2006, Harvest Vinccler entered into a term loan with a Venezuelan bank for 20 billion Bolivars (approximately $9.3 million). The loan matures in 180 days at a fixed interest rate of 10.0 percent. The loan was used to meet the SENIAT income tax assessments and related interest. This loan is collateralized by a $7.7 million deposit plus interest in a U.S. bank. This loan matured on April 2, 2007. At maturity, Harvest Vinccler and the Venezuelan bank agreed to extend the loan for an additional 180 days subject to the same terms and conditions.
     On November 20, 2006, Harvest Vinccler entered into a three year term loan with a Venezuelan bank for 120 billion Bolivars (approximately $55.8 million). The first principal payment is due 180 days after the funding date in the amount of 20 billion Bolivars (approximately $9.3 million), and 20 billion Bolivars (approximately $9.3 million) every 180 days thereafter. A payment in the amount of 15 billion Bolivars (approximately $7.0 million) was made on February 2, 2007. The interest rate for the first 180 days is fixed at 10.0 percent and may be adjusted from time to time thereafter within the limits set forth by the Central Bank of Venezuela or in accordance with the conditions in the financial market. The loan is collateralized by a $35.4 million deposit plus interest in a U.S. bank. The loan was used to meet the SENIAT income tax assessments and related interest, refinance a portion of the 105 billion Bolivar loan and to fund operating requirements.

Note 3 — Commitments and Contingencies
     Excel Enterprises L.L.C. vs. Benton Oil & Gas Company, now known as Harvest Natural Resources, Inc., Chemex, Inc., Harvest Vinccler, C.A., Gale Campbell and Sheila Campbell in the District Court for Harris County, Texas. This suit was brought in May 2003 by Excel alleging, among other things, breach of a consulting agreement between Excel and us, misappropriation of proprietary information and trade secrets, and fraud. Excel seeks actual and exemplary damages, injunctive relief and attorneys’ fees. In October 2003, the Court abated the suit pending final judgment of a case pending in Louisiana to which we are not a party. We dispute Excel’s claims and plan to vigorously defend against them. We are unable to estimate the amount or range of any possible loss.
     Uracoa Municipality Tax Assessments. Harvest Vinccler has received nine assessments from a tax inspector for the Uracoa municipality in which part of the SMU fields are located as follows:
    Three claims were filed in July 2004 and allege a failure to withhold for technical service payments and a failure to pay taxes on the capital fee reimbursement and related interest paid by PDVSA under the Operating Services Agreement. Harvest Vinccler has filed a motion to enjoin and dismiss one of the claims with the Tax Court in Barcelona, Venezuela and has protested the remaining claims with the municipality.
 
    Two claims were filed in July 2006 alleging the failure to pay taxes at a new rate set by the Municipality. Harvest Vinccler has filed a protest on these claims with the Tax Court in Barcelona.
 
    Two claims were filed in August 2006 alleging a failure to pay taxes on estimated revenues for the second quarter of 2006 and a withholding error with respect to certain vendor payments. Harvest Vinccler has filed a protest on one claim with the Tax Court in Barcelona and filed a protest on the other claim with the municipality.
 
    Two claims were filed in March 2007 alleging a failure to pay taxes on estimated revenues for the third and fourth quarters of 2006. Harvest Vinccler has filed a protest on these claims with the municipality.
Harvest Vinccler disputes the Uracoa tax assessments and believes it has a substantial basis for its positions. Harvest Vinccler is unable to estimate the amount or range of any possible loss. As a result of retroactive tax increases imposed by the SENIAT, the Venezuelan income tax authority, Harvest Vinccler has filed claims against the Uracoa Municipality in the Tax Court in Caracas for the refund of all municipal taxes paid since 1997.
     Libertador Municipality Tax Assessment. In April 2005, Harvest Vinccler received a tax assessment from a tax inspector for the Libertador municipality in which part of the SMU fields are located. Harvest Vinccler has submitted a protest to the assessment at the Mayor’s Office, and if no favorable resolution is obtained, it will file a motion with the tax court seeking to enjoin the payment order and dismiss the assessment. We dispute the allegations set forth in the assessment and believe we have a substantial basis for our position. We are unable to estimate the amount or range of any possible loss. As a result of retroactive tax increases imposed by the SENIAT, the Venezuelan income tax authority, Harvest Vinccler has filed claims against the Libertador Municipality in the Tax Court in Caracas for the refund of all municipal taxes paid since 2001.
     International Arbitration. As a result of the actions taken by PDVSA, the Ministry of Energy and Petroleum (“MEP”) and the SENIAT, in July 2005, we delivered formal notices to Venezuelan government officials of an investment dispute under Venezuelan law and bilateral investment treaties entered into by the government of Venezuela. The bilateral investment treaties and Venezuelan law provide for international arbitration of investment disputes conducted through the International Centre for Settlement of Investment Disputes of the World Bank.
     We are a defendant in or otherwise involved in other litigation incidental to our business. In the opinion of management, there is no such litigation which will have a material adverse impact on our financial condition, results of operations and cash flows.

     In July 2006, the FASB issued Financial Interpretation No. 48 (“FIN 48”) – Accounting for Uncertainty in Income Taxes. FIN 48 was issued to create a single model to address accounting for uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes by prescribing a recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 did not impact our consolidated financial position, results of operations and cash flows for the quarter ended March 31, 2007.
Note 5 — Operating Segments
     We regularly allocate resources to and assess the performance of our operations by segments that are organized by unique geographic and operating characteristics. The segments are organized in order to manage regional business, currency and tax related risks and opportunities. As a result of the situation in Venezuela, our GAAP consolidated financial statements for the three months ended March 31, 2007 do not reflect the net results of our producing operations in Venezuela. See Note 7 – Venezuela, Operations. Revenue from Venezuela is derived primarily from the delivery and sale of oil and natural gas. Operations included under the heading “United States and Other” include corporate management, cash management, business development and financing activities performed in the United States and other countries which do not meet the requirements for separate disclosure. All intersegment revenues, other income and equity earnings, expenses and receivables are eliminated in order to reconcile to consolidated totals. Corporate general and administrative and interest expenses are included in the United States and Other segment and are not allocated to other operating segments:

     In March 2007, China National Offshore Oil Corporation (“CNOOC”) granted us an extension of Phase 1 of the Exploration Period for the WAB-21 contract area to May 2009. WAB-21 represents the $2.9 million excluded from the full cost pool as reflected on our March 31, 2007 and December 31, 2006 balance sheets.
Note 7 — Venezuela Operations
South Monagas Unit, Venezuela (Harvest Vinccler)
     Currently, our only producing assets are in Venezuela. Since 1992, Harvest Vinccler has been providing operating services to PDVSA for the South Monagas Unit under an OSA. However, beginning in 2005, the government of Venezuela initiated a series of actions to compel companies with operating service agreements to convert those agreements into new companies in which PDVSA would have a majority interest. On March 31, 2006, Harvest Vinccler signed a MOU with two affiliates of PDVSA, CVP and PPSA, to convert the OSA into a minority interest in Petrodelta. The MOU is subject to certain conditions, including execution of the Conversion Contract and Venezuelan government approvals. On August 16, 2006, the MOU was amended to provide for the addition of the Isleño, El Salto and Temblador fields to Petrodelta as additional consideration for our conversion of the OSA to Petrodelta. On December 18, 2006, at a Special Meeting of the Stockholders of Harvest Natural Resources, Inc., the transactions contemplated by the MOU were approved. As of this report, the Minister of Energy and Petroleum has approved this agreement. We await further governmental approvals necessary to complete the conversion, however, the timing of and probability for such approval is uncertain.
     In April 2006, the Venezuelan National Assembly passed legislation terminating all operating service agreements and directing the government to take over the operations carried out by the private companies without prejudice to the incorporation of mixed companies for that purpose. This action, coupled with the unfinished conversion to Petrodelta, has left Harvest Vinccler without a contractual means recognized by the government of Venezuela to address revenues or costs and expenses since March 31, 2006. As a result of this situation, our consolidated financial statements prepared in accordance with GAAP for the year ended December 31, 2006 and the three months ended March 31, 2007, do not reflect the net results of our producing operations in Venezuela. We will not be able to include the results of our Venezuelan operations in our consolidated financial statements until the conversion to Petrodelta is completed or there is a contractual means recognized by the government of Venezuela to address revenues, costs and expenses. Although the MOU provides that upon completion of the conversion, there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006, this adjustment will not occur until the conversion is completed.
     Since signing the MOU, CVP has designated its board members and a General Manager and President for Petrodelta, each of whom influence Harvest Vinccler’s operations and staffing. Harvest Vinccler continues in the day-to-day operations of its properties in Venezuela, and since April 1, 2006, it has accrued cash advances of $46.1 million to fund operations. At the request of PDVSA, Harvest Vinccler invoiced PDVSA for these costs and as of April 25, 2007, $35.4 million, representing April through December 2006 advances, have been reimbursed. Harvest Vinccler invoiced PDVSA $6.9 million for January and February 2007 expenses and has received partial reimbursement for January.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Harvest Natural Resources, Inc. (“Harvest” or the “Company”) cautions that any forward-looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995) contained in this report or made by management of the Company involve risks and uncertainties and are subject to change based on various important factors. When used in this report, the words “budget”, “guidance”, “forecast”, “anticipate”, “expect”, “believes”, “goals”, “projects”, “plans”, “anticipates”, “estimates”, “should”, “could”, “assume” and similar expressions are intended to identify forward-looking statements. In accordance with the provisions of the Private Securities Litigation Reform Act of 1995, we caution you that important factors could cause actual results to differ materially from those in the forward-looking statements. Such factors include our concentration of operations in Venezuela, the political and economic risks associated with international operations (particularly those in Venezuela), the anticipated future development costs for our undeveloped reserves, conversion of Venezuelan assets to a mixed company, the risk that actual results may vary considerably from reserve estimates, the dependence upon the abilities and continued participation of certain of our key employees, the risks normally incident to the operation and development of oil and natural gas properties, risks incumbent to being a minority shareholder in a corporation, the permitting and the drilling of oil and natural gas wells, the availability of materials and supplies necessary to projects and operations, the price for oil and natural gas and related financial derivatives, changes in interest rates, basis risk and counterparty credit risk in executing commodity price risk management activities, the Company’s ability to acquire oil and natural gas properties that meet its objectives, changes in operating costs, overall economic conditions, political instability, civil unrest, acts of terrorism, currency and exchange risks, currency controls, changes in existing or potential tariffs, duties or quotas, changes in taxes, changes in governmental policy, availability of sufficient financing, changes in weather conditions, and ability to hire, retain and train management and personnel. A discussion of these factors is included in our Annual Report on Form 10-K for the year ended 2006, which includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Quarterly Report.
Venezuela
     We had a loss of $6.5 million, or $0.17 per diluted share, for the three months ended March 31, 2007. The loss is due to the continued inability to recognize equity earnings for the producing operations in Venezuela. As we described in our Annual Report on Form 10-K for the year ended 2006, we will not be able to report the results of our Venezuelan operations in our consolidated financial statements until the conversion to Petrodelta S.A. (“Petrodelta”) is completed or there is a contractual means recognized by the government of Venezuela to address revenues, costs and expenses. Although the Memorandum of Understanding executed by Harvest Vinccler, Corporación Venezolana del Petroleo S.A. (“CVP”) and PDVSA Petroleo S.A. (“PDVSA”) in March 2006 provides that upon completion of the conversion there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006, this adjustment will not occur until the conversion is completed. Conversion cannot be completed until Harvest Vinccler receives all required approvals by the government of Venezuela. Based on our ongoing discussions with Venezuelan officials, we believe that these approvals will be received, but we cannot provide assurance when or if that will occur.
     Through April 2007, we have been reimbursed $15.1 million by PDVSA for advances to fund operations during the fourth quarter of 2006. We have invoiced PDVSA for January and February 2007 advances of $6.9 million and have been reimbursed for most of the January advances. We have also reached agreement with CVP on the business plan for Petrodelta. Our plan calls for the immediate resumption of the suspended development of the SMU fields as well as appraisal and development of the Isleño, Temblador and El Salto fields. We believe these events show continued progress to conversion to Petrodelta.
     Certain operating statistics for the three and twelve month periods ended March 31, 2007 for the SMU fields operated by Harvest Vinccler are set forth below. This information is provided at 100 percent, without reduction for our interest under the Operating Services Agreement (“OSA”) or an ownership interest in Petrodelta. While we believe this information to be accurate, no representation is made with respect to what will be reflected in our consolidated financial statements after completing the conversion to Petrodelta. This information may not be representative of future results.

     Crude oil delivered from the SMU fields to PDVSA will be priced with reference to Merey 16 published prices, weighted for different markets and adjusted for variations in gravity and sulphur content, commercialization costs and distortions that may occur given the reference priced and prevailing market conditions. Crude oil prices that would be paid for the oil production if the Conversion Contract were in place cannot yet be calculated as an element of the pricing formula has not been set. Market prices for crude oil of the type produced in the fields operated by Harvest Vinccler averaged approximately $44.43 and $47.18 a barrel for the three and twelve months ended March 31, 2007, respectively. The price for natural gas that would be paid under the Conversion Contract is $1.54 per thousand cubic feet.

Capital Resources and Liquidity
     Debt Reduction. We have semi-annual principal obligations of $9.8 million and $9.3 million on the Harvest Vinccler loans. We have no other debt obligations.
     Working Capital. Our capital resources and liquidity are affected by the conversion to Petrodelta and the ability of Petrodelta to declare dividends.
     The net funds raised and/or used in each of the operating, investing and financing activities are summarized in the following table and discussed in further detail below:

Net increase (decrease) in cash
  $ (9,373 )   $ 22,685  
 
           
     At March 31, 2007, we had current assets of $196.6 million and current liabilities of $77.6 million, resulting in working capital of $119.0 million and a current ratio of 2.5:1. This compares with a working capital of $117.6 million and a current ratio of 2.4:1 at December 31, 2006. The increase in working capital of $1.4 million was primarily due to a minimal production-related expenditure program.
     Cash Flow from Operating Activities. During the three months ended March 31, 2007, net cash used in operating activities was approximately $10.7 million. During the three months ended March 31, 2006, net cash provided by operating activities was approximately $27.1 million. The $37.8 million decrease was primarily due to our inability to recognize results of operations from producing properties in Venezuela since April 1, 2006.
     Cash Flow from Investing Activities. During the three months ended March 31, 2007 and 2006, we had limited production-related capital expenditures. In January 2007, we purchased a 45 percent interest in Fusion Geophysical, L.L.C. for $4.6 million. Restricted cash of $13.8 million was released and returned to us during the three months ended March 31, 2007. During the three months ended March 31, 2006, we had workover and production-related expenditures of approximately $1.5 million. The lack of capital expenditures is due to the

15


Table of Contents

continued suspension of our drilling program and the fact that the conversion of the OSA to Petrodelta has not been finalized. We continue to advance funds during the period prior to the conversion for maintenance of the existing wells. After the conversion to Petrodelta, our capital commitments will be determined by the business plan provided for in the Conversion Contract and the annual budget approved by the Petrodelta Board of Directors to implement the business plan. Outside of Venezuela, our capital commitments support our business development efforts and are substantially at our discretion.
     Cash Flow from Financing Activities. During the three months ended March 31, 2007, Harvest Vinccler repaid 15 billion Bolivars (approximately $7.0 million) of its Bolivar denominated debt. During the three months ended March 31, 2006, Harvest Vinccler repaid $2.9 million of its U.S. Dollar denominated debt (one payment of $0.3 million and two payments of $1.3 million each on the variable rate loans).
Results of Operations
     You should read the following discussion of the results of operations for the three months ended March 31, 2007 and 2006 and the financial condition as of March 31, 2007 and December 31, 2006 in conjunction with our consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended 2006.
Three Months Ended March 31, 2007 Compared with Three Months Ended March 31, 2006
     We reported a net loss of $6.5 million, or $0.17 diluted earnings per share, for the three months ended March 31, 2007 compared with net income of $13.9 million, or $0.36 diluted earnings per share, for the three months ended March 31, 2006.
Total expenses and other non-operating (income) expense (in millions):
                         
             
    Three Months Ended        
    March 31,     Increase  
    2007     2006     (Decrease)

  $ 6.6     $ 7.3     $ (0.7 )
 
                 
     General and administrative expense decreased due to lower business development activities. Taxes other than on income decreased due to the elimination of municipal taxes which are based on oil and gas revenues.
     Investment earnings and other increased due to higher interest rates earned on cash balances. Interest expense increased due to higher average outstanding debt balances in the three months ended March 31, 2007 compared with 2006.
     Income tax expense decreased $14.6 million due to lower taxable income as a result of our inability to recognize the results of our Venezuelan operations.
Effects of Changing Prices, Foreign Exchange Rates and Inflation
     Our results of operations and cash flow are affected by changing oil prices. Fluctuations in oil prices may affect our total planned development activities and capital expenditure program.
     Venezuela imposed currency exchange restrictions in February 2003, and adjusted the official exchange rate in February 2004 and again in March 2005. We do not expect the currency conversion restrictions or the adjustment in the exchange rate to have a material impact on us at this time. Within the United States, inflation has had a minimal effect on us, but it is potentially an important factor with respect to results of operations in Venezuela.

Table of Contents

     During the three months ended March 31, 2007, our net foreign exchange gains attributable to our international operations were minimal. The U.S. Dollar and Bolivar exchange rates have not been adjusted since March 2005. However, there are many factors affecting foreign exchange rates and resulting exchange gains and losses, most of which are beyond our control. We have recognized significant exchange gains and losses in the past, resulting from fluctuations in the relationship of the Venezuelan currency to the U.S. Dollar. It is not possible for us to predict the extent to which we may be affected by future changes in exchange rates and exchange controls.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
     We are exposed to market risk from adverse changes of the situation in Venezuela, and adverse changes in oil, interest rates, foreign exchange and political risk, as discussed in our Annual Report on Form 10-K for the year ended 2006. The information about market risk for the three months ended March 31, 2007 does not differ materially from that discussed in the Annual Report on Form 10-K for the year ended 2006.
Item 4. Controls and Procedures
     The Securities and Exchange Commission (“SEC”), among other things, adopted rules requiring reporting companies to maintain disclosure controls and procedures to provide reasonable assurance that a registrant is able to record, process, summarize and report the information required in the registrant’s quarterly and annual reports under the Securities Exchange Act of 1934 (the “Exchange Act”). While we believe that our existing disclosure controls and procedures have been effective to accomplish these objectives, we intend to continue to examine, refine and formalize our disclosure controls and procedures and to monitor ongoing developments in this area. There have not been any changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) or 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
     Evaluation of Disclosure Controls and Procedures. We have established disclosure controls and procedures to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.
     Based on their evaluation as of March 31, 2007, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) under the Exchange Act) are effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is 1) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and 2) accumulated and communicated to our management, including our principal executive and principal financial officers, to allow timely decisions regarding required disclosure.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
    Uracoa Municipality Tax Assessments. Harvest Vinccler has received nine assessments from a tax inspector for the Uracoa municipality in which part of the SMU fields are located as follows:
    Three claims were filed in July 2004 and allege a failure to withhold for technical service payments and a failure to pay taxes on the capital fee reimbursement and related interest paid by PDVSA under the Operating Services Agreement. Harvest Vinccler has filed a motion to enjoin and dismiss one of the claims with the Tax Court in Barcelona, Venezuela and has protested the remaining claims with the municipality.
 
    Two claims were filed in July 2006 alleging the failure to pay taxes at a new rate set by the Municipality. Harvest Vinccler has filed a protest on these claims with the Tax Court in Barcelona.
 
    Two claims were filed in August 2006 alleging a failure to pay taxes on estimated revenues for the second quarter of 2006 and a withholding error with respect to certain vendor payments. Harvest Vinccler has filed a protest on one claim with the Tax Court in Barcelona and filed a protest on the other claim with the municipality.
 
    Two claims were filed in March 2007 alleging a failure to pay taxes on estimated revenues for the third and fourth quarters of 2006. Harvest Vinccler has filed a protest on these claims with the municipality.
    Harvest Vinccler disputes the Uracoa tax assessments and believes it has a substantial basis for its positions. Harvest Vinccler is unable to estimate the amount or range of any possible loss. As a result of retroactive tax increases imposed by the SENIAT, the Venezuelan income tax authority, Harvest Vinccler has filed claims against the Uracoa Municipality in the Tax Court in Caracas for the refund of all municipal taxes paid since 1997.
 
    Libertador Municipality Tax Assessment. In April 2005, Harvest Vinccler received a tax assessment from a tax inspector for the Libertador municipality in which part of the SMU fields are located. Harvest Vinccler has submitted a protest to the assessment at the Mayor’s Office, and if no favorable resolution is obtained, it will file a motion with the tax court seeking to enjoin the payment order and dismiss the assessment. We dispute the allegations set forth in the assessment and believe we have a substantial basis for our position. We are unable to estimate the amount or range of any possible loss. As a result of retroactive tax increases imposed by the SENIAT, the Venezuelan income tax authority, Harvest Vinccler has filed claims against the Libertador Municipality in the Tax Court in Caracas for the refund of all municipal taxes paid since 2001.
